Esta obra está no domínio público nos Estados Unidos porque foi publicada (ou registada no U.S. Copyright Office) antes de 1 de janeiro de 1930.

Works copyrighted before 1964 had to have the copyright renewed sometime in the 28th year. If the copyright was not renewed the work is in the public domain. No renewal notice found for the National Editorial Association/Associated Press and the Detroit News etc. for items published in the year 1927. For instance I can find a renewal notice for the New York Times for this year. If you find a renewal notice under a variation of the name of the publication, or a successor name of the publication, or any other evidence to the contrary, notify me and I will delete this.

Note: No renewal notice found for Benton Harbor News Palladium (publication of this photo seen here), or for The Detroit News, or for National Editorial Association/Associated Press in the Stanford copyright renewal database at https://exhibits.stanford.edu/copyrightrenewals for the following terms "Ellsworth", "Bath", "Bath School", "Bath School disaster", "National Editorial Association", "Associated Press". Searches of the UPenn database at https://onlinebooks.library.upenn.edu/cce/ and of the various Copyright volumes also provided no pertinent search results.
